[0027] As Figures 1-5 shown:

[0028] The inner torx screw comprises a screw rod 1 and a screw head 2 connected to the screw rod 1, the top of the screw head 2 is provided with an inner torx groove 21, and the outer wall of the lower end of the screw rod 1 is provided with a thread 11; the screw rod 1 is sequentially sleeved with a second gasket 4 and a first gasket 3, and the first gasket 3 and the second gasket 4 are located above the thread 11; the lower end surface of the screw head 2 is provided with a first anti-slip tooth 22, the upper end surface of the first gasket 3 is provided with a second anti-slip tooth 31 matched with the first anti-slip tooth 22, and the first anti-slip tooth 22 and the second anti-slip tooth 31 are matched to prevent loosening; the second gasket 4 is sealingly connected with the screw rod 1; and the material of the second gasket 4 is rubber.

[0029] When the inner torx screw is loosened, the screw head 2 rotates counterclockwise relative to the first gasket 3, and the second anti-slip tooth 31 on the first gasket 3 blocks the first anti-slip tooth 22 on the screw head 2 from continuously rotating counterclockwise to achieve the loosening effect.

[0030] The beneficial effects are that the first anti-slip tooth 22 and the second anti-slip tooth 31 are matched to achieve screw anti-loosening, the second gasket 4 prevents the screw from scratching and scratching the contact surface during screw installation, in addition, the sealing connection between the second gasket 4 and the screw rod 1 achieves dustproof and waterproof sealing of the screw, finally realizes the "three-proofing" of the screw, that is, anti-loosening, waterproof and dustproof, and finally improves the fastening effect of the inner torx screw and prolongs the service life. The material of the second gasket 4 is preferably rubber, which has good sealing performance, and the rubber also has good elasticity, which provides a buffer between the first gasket 3 and the contact surface, has a damping effect, and the second gasket 4 can increase the friction between it and the first gasket 3 and the contact surface, also has the effect of anti-loosening; the second gasket 4 can also prevent the contact surface from being scratched and scratched, especially can prevent the paint surface from being damaged.

[0031] Preferably, the first anti-slip tooth 22 comprises a plurality of first tooth tips 221 and a plurality of first recesses 222, each first tooth tip 221 is protruded on the lower end surface of the screw head 2, and any two adjacent first tooth tips 221 are respectively accommodated between each first recess 222.

[0032] Preferably, the upper end surface of the first gasket 3 is provided with a groove 32, and the groove 32 is circumferentially arranged on the side close to the screw rod 1.

[0033] Preferably, the groove 32 is provided with the second anti-slip tooth 31, and the second anti-slip tooth 31 comprises a plurality of second tooth tips 311 and a plurality of second recesses 312, each second tooth tip 311 is protruded on the plane where the groove 32 is located, and any two adjacent second tooth tips 311 are respectively accommodated between each second recess 312.

[0034] Preferably, the tooth top of the second tooth tip 311 is flush with the upper end surface of the first gasket 3.

[0035] It should be noted that in general, the first tooth tip 221 is located in the second recess 312, and the second tooth tip 311 is located in the first recess 222, when the screw is loosened, the screw head 2 rotates counterclockwise relative to the first gasket 3, at this time, the second tooth tip 311 will block the first tooth tip 221, preventing the screw head 2 from continuing to rotate counterclockwise relative to the first gasket 3, so as to achieve the screw anti-loosening effect.

[0036] Preferably, the first gasket 3 covers the second gasket 4.

[0037] Preferably, the protrusion 12 is arranged on the screw rod 1 along the circumferential direction of the screw rod 1, the protrusion 12 is located above the thread 11, the first gasket 3 abuts against the protrusion 12, and the protrusion 12 is in sealing connection with the first gasket 3.

[0038] The beneficial effect is that the protrusion 12 is used to cooperate with the first gasket 3 to improve the sealing performance, and has the effects of waterproofing and dustproofing.

[0039] Preferably, the first gasket 3 comprises a through hole through which the screw rod 1 passes, and the diameter of the protrusion 12 is greater than the diameter of the through hole.

[0040] Water and dust entering the through hole will be blocked by the protrusion 12, preventing them from further penetrating into the screw, preventing internal rusting of the screw, and prolonging the service life of the screw.

[0041] Preferably, the material of the first gasket 3 is metal.

[0042] When the screw is loosened, the first tooth tip 221 will contact the second tooth tip 311, so the first gasket 3 is preferably made of metal, so as to have a certain strength, so as to reduce or prevent the second anti-skid tooth 31 from deforming in the process of continuously contacting the first anti-skid tooth 22.
